leave变完成时要改成be away 还是be away from?
Jenny has (left) Canada for three years.
括号里的left应该换成been away from 还是been away?
如果是been away的话语法正确吗?away后面可以直接加地点吗?

for three years指一段时间,故用现在完成时态
left是短暂性动词,需改为延续性动词,故是been away from (强调状态)
而been away后必须加介词才能跟地点Canada
所以是been away from

leave变完成时要改成be away 还是be away from? be away from 与leave的区别 be ...away from造句 be away from sb. be held away from be away from,be away of,be away for Leave和 be away from 表示“离开”时,有什么区别? far away,far from,far away from ,be away ,be away from的区别关于be far away from 英语翻译 be away from Please be far away from be away from啥意思?
